Sensor Net Makes Life Easier for Rice Farmers
Rice is cultivated all over the world in fields known as rice paddies and it is one of the most maintenance intensive crops to grow. The rice paddy itself requires a large part of that maintenance. It is flooded with water that must be kept at a constant level, just below the height that would keep rice seedlings from growing but high enough to drown any weeds that would compete with the rice stalks for nutrients. This technique is called continuous flooding and a big part of the job of a rice farmer is to inspect the rice paddy every …read more
Radial Solenoid Engine is Undeniably Cool
Radial engines are just plain cool – it’s inarguable that any tech that originated with early aviation is inherently awesome. But, what do you do when you want to build a radial engine in your dorm where a combustion engine would be inadvisable? For University of Washington students [Jeffrey Weng] and [Connor Lee] the answer was to power it with solenoids in place of the pistons.
The easiest way to approach a project like this would have been to use a microcontroller. A simple program running on an Arduino could have easily provided the timing to switch power to each …read more

The Square Inch Project Challenges Your Layout Skills
[alpha_ninja] proves that Hackaday.io is not just about great projects, but about an awesome community. Over this past week [alpha_ninja] has created The Square Inch Project, which is a grass-roots contest. The contest rules are pretty simple: The project PCB must fit in a 1″ x 1″ square. That’s 2.54 cm for those that don’t use freedom units. Smaller than a square inch is fine. If the project has multiple PCBs like a cordwood module, ALL the PCBs must still fit within the 1″ x 1″ square. Hackaday.io users coming up with cool contest ideas and inviting everyone to take …read more
A White Hat Virus for the Internet of Things
The Internet of Things is going gangbusters, despite no one knowing exactly what it will be used for. There’s more marketing money being thrown at IoT paraphernalia than a new soda from Pepsi. It’s a new technology, and with that comes a few problems: these devices are incredibly insecure, and you only need to look at a few CCTV camera streams available online for proof of that.
The obvious solution to vulnerable Internet of Things things would be to get people to change the login credentials on their devices, but that has proven to be too difficult for most of …read more
